Hi! I’m a newer hobbyist when it comes to saltwater tanks and about two weeks ago I got my first coral. It is a pulsing Xenia and for the first few days I had it it was beautiful. However I noticed it began to shrivel up day by day till I noticed aptasia growing around and on it. I got a peppermint shrimp today but I just want to ask if anyone has any other tips, because if it’s not the aptasias fault for my coral dying then I don’t know what is. I do regular water changes and my water perimeters are near perfect. Please someone help.
